Study on North Early-matured Spring Maize Germplasm Enhancement and Utilization |
| |
| Abstract: | The main problems which hinder maize breeding and improving production level were ack of maize germplasm resources and the genetic foundation, the primary mission for maize breeding was to develop research of north early-matured spring maize germplasm enhancement and utilization. The ways, methods and achievements that were utilized in maize germplasm enhancement and utilization were briefly described in this paper. Research was done on germplasm enhancement including maize population improvement of narrow gene, introduction to improvement of maize synthetic populations, mutual introduction between tropical, subtropical and temperate corn germplasm, breeding of resistance inbred line also. |
